Star Wars producers filmed desert scenes of the film's planet Tatooine
1 . Notice the sand dunes of the Algodones Dune Field in FIGURE 19 .1 . Why do you think there are no plants growing on
the dunes
reach velocities up to 60 miles per hour . This can create hazardo

the need for maintainence on the canal and Interstate Route 8 . What would be the hazard , and what maintenance would
be needed periodically on the canal and Interstate Route 8 as a result of the hazard ?
3 . This region is managed by the U
the U .S . Bureau of Land Management as Imperial Sand Dunes Recreation Area . Portions of the
dunes are available for operating off - road vehicles
vehicles . What effi
at effect do you think the operation of off -road vehicles here would
have on plant growth and the hazards you described above ?
Death Valley , occurs in the Mojave Desert . Analyze the images of the Death Valley region in FIGURES 14 .2 and 14. 3
1 . Notice in FIGURE 14 .2 that steep mountain
mountainous slopes occur on both sides of Death Valley . Also notice that there is
almost no soil or vegetation on the slopes . Describe what you think conditions would be like in the river va
leys on these
mountain s
slopes when a heavy rain falls on them
2 . Notice the delta- like landforms that form at the mou
this of the rivers in FIGURES 14 .2 and 14 .3 , where the rivers enter t
valley . Explain how you think these landforms form
3 . Notice that there is no standing water in Death Valley , even though you can see that water sometimes flows into the valley
from the mountains . It is a closed basin ( meaning that water has no way to drain from it ) . It is also the hottest and driest
place in North America . When there is water on the floor of the vally , it is alkaline to salty and not parable ( drinkable
How do you think the water gets so alkaline and salty ?

D . REFLECT & DISCUSS The United Nations Convention to Combat Desertification ( UNCCD ) points out that many
people live in drylands , and that more than half of the world's productive land is dryland . The challenge is to manage the land
so that it does not degrade to useless desert that supports no agriculture , and to live safely Based on your work above , make a
list of challenges that people face when they live in drylands , and some ways that the lan
and more productive
